US citizens in Sydney warned to avoid Martin Place and Hyde Park

The United States has warned its citizens to keep away from Sydney’s Martin Place and Hyde Park this weekend amid fears of another outbreak of violence.

A letter titled “Emergency Message for US Citizens” sent to all those registered with the US consulate says that “law enforcement authorities” have advised that anti-American demonstrations are possible on both Saturday and Sunday.

It also warns Melbourne residents to avoid protest areas planned in this city this weekend.

“Should they occur, US citizens should avoid the immediate demonstration areas,” the letter reads.

“Fast-forming anti-American protests in Australia remain possible.”

A spokeswoman for the US consulate told Fairfax Media that the last time such a warning was issued to its citizens was for the Queensland floods in early 2011.

The letter also urges Americans to avoid attracting attention to themselves as US citizens.

“The Department of State remains concerned about the threat of violence against US citizens and interests throughout the world. US citizens are reminded to maintain a high level of vigilance, to be aware of their surroundings and to take appropriate steps to increase their security awareness,” it reads.
